Ian Grigg notes that the one-click payment systems of e-cash was already there before Amazon invented (and patented) their system. Which leads to the question: is there really much to patent in payments?
Technically perhaps, but in a functional way money needs to go from A to B. So while many keep on dreaming of making money by inventing payment mechanisms, they better focus on selling something rather than doing this payment stuff.
Before you know, you end up signing your own regulatory measures.. ;-)
